[GAMEPLAY]Katarina Spells not useable, Video Proof

In a ranked game I played Katarina and after a hectic teamfight around dragon, i was backing away with little health. I walked into our jungle and stood upon a reksai tunnel (my teammate) and pressed b, but nothing happened. while walking back to base i thought my keyboard disconnected, but after checking my ward trinket it still responded, aswell as chat. recalling, either through pressing B or clicking the recall button did not work. (32 minutes into the game) In the Video i was testing the spells live during the ranked game on the golems. The results i got from using them on the golems was replicable everywhere else with all other enemies, etc. Sadly i couldnt get the Death lotus not working on video as, you know, it was live in a game and the enemies were not ready to give me a clean try on them for experimenting. As the game dragged out i couldnt use my spells still, resorting to me trying to just wait at the back of a fight and not feed. just in the end on the last teamfight i got cc'd hard by maokai and then my ult at least (after the cc) worked. my q still didnt respond, nor did recalling. I can assure you tough, that the ult was not working for qutie a while, as i got an opportunity to try it while chased by the enemies and having them even close by, but didnt catch it on tape as i wasnt recording the game (only the testing bit).

My guess is it had something to do with Crowd Control, and if so, it was Crowd Control by Maokai and Nautilus (Maokai with the Christmas Skin)
